'2 Claims. (Cl. 226-2)' Thi invention relates to a machine for loadingbread dough or the like in baking pans and more particularly relates toa machine for automatically advancing units of bake pans each of whichmay include a plurality of pans, one panwidth at a time intermittentlypast a loading station so that each pan receives a lump of dough as itmoves past the loading station.

An object of this invention is to provide a machine which automaticallyadvances and stops bread pans one at a time at a loading station anddrops a loaf or lump of dough into each pan while at rest at the loadingstation.

A further object of this invention is to provide a machine for loadingloaves or lumps of dough into baking pans in which machine dough loavesare advanced to a position above a loading station and dropped intobaking pans as the pans are arrested at the loading station.

A further object of this invention is to provide a machine for loadingdough loaves into baking pans in which the dough loaves are carried pasta stop releasing member which releases a pan to advance to the loadingstation where the pan is arrested before the dough loaf drops from thedough conveyor to the pan.

A further object of this invention is to provide a machine of this typehaving a stop member at a pan holding station on the pan conveyor .be-

yond the loading station at which a loaded pan is arrested to halt a rowof following pans on the conveyor including a pan at the loadingstation.

A further object of this invention is to provide a pan'stopping memberin a machine of this type having a plurality of pan stopping arms eachadapted to extend a limited distance into a loaded Dan insuflicient tosubstantially displace a dough permit a pan at the pan loading stationto be released, the pan stopping member being adapted to arrest the nextfollowing pan as it reaches the pan holding station so that a pan isadvanced to the pan loading station when the pawl is released.

A further object of this invention is to provide a mechanism forautomatically timing intermittent movement of bake pans over acontinuously 'moving conveyor with respect to the movement of individuallumps or loaves of dough moving v "on-asuperposed conveyor so that themovement of the pans is arrested at the time a dough lump is dischargedfrom its conveyor at such a position that each pan receives a loaf orlump of dough.

The above and other objects and features of the invention will in partbe apparent and will in part be obvious from the following detaileddescription and the drawings, in which:

Figure l is a view in side elevation showing a pan loading machineconstructed inlaccordance with an embodiment of this invention; and

Fig. 2 is a view in end elevation of the machine illustrated in Fig. 1,the conveyor for receiving pans from the pan loading machine being shownin section, a part of an end plate of the machine being broken away toreveal structural details.

In the following detailed description and the drawings, like referencecharacters indicate like parts.

As shown in the drawings the machine includes a framework comprising apair of side members l0 and a front plate l2 extending between the sidemembers ID. A roll I3 extends -between and is rotatably supported in theside members It. A belt [4 runs on roll 13 and conveys bread bake panunits tandemwise inthe direction indicated. Each unit includes aplurality of individual baking pans I6.-- The belt [4 delivers the pansl6 onto'a table I! along which they are moved by the pans on theconveyor belt.

The baking pans may be of the type commonly used in baking bread, and aplurality of pans may be joined together to form the pan units by meansof pan straps l8. The pans are advanced by the belt I! one afteranother, and as the pans leave the belt, the pans are driven past aloading station and a pan holding station. A pan at the loading stationis indicated at 16c, while a pan at the pan holding station is indicatedat'Hib. A stop member,- indicated generally at [9 in Fig. l is adaptedto engage each pan as it reaches the pan holding station to arrestmovement of the entire group of pans on the table [1. p The belt [4 isnot stopped so that when the pans are stopped they slide relative to thebelt. When movement of the pans is arrested, one of the individual panswill be in positiion to receive a as shown in ,Fig. 1.

to carry a dough loaf 26 to a position above the pan at the loadingstation 16a, and the dough loaf fall from the dough conveyor 24 into thepan at the loading station 16a. A dough loaf is indicated at 26a in itsposition immediately before reaching the pan at the loading station lGa.A dough loaf guiding member 2'! is attached to the dough conveyor.framework '22 Opposite the roll 23 and is adapted to guide dough loavesand direct them into the pan at the loading station Ilia.

Release frame members 28 are attached to and extend upwardly from thedough conveyor framework a short distance ahead of the roll 23. Thesupport members 28 rotatably support a xtransverse bar 29 to which isattached a release :flap :31. As shown in the drawings, the release flap3i is disposed in the path of the dough loaves on the dough conveyorbelt 24, and the release flap normally is held inclined to thehorizontaleas shown in Fig. 1, so that, when a dough loaf comes againsttheneleasefiap, the dough loaf raises therelease ma ;-t,o.s,wing the bar29in a clockwise direction When the loaf has passed beyond the flap 3i,the flap returns to its normal position. A crankBZ is attached to thebar29 to swing with-the release-flap. A .link'Si! extends between thecrank 32 and an elongated pawl carrying rod .34. Th pawl carrying rod 34in turn .is pivotally attached to the .dough --conveyor iramework. Apivoting 38 is rotatably mounted on an ear 3! attached to the doughconveyor framework 22.. The ;pawl carrying rod 34 is'attaohed to .thelug .31, as clearly shown in the (drawings and swings about the axis ofthe lug 31.

The rod 34 and associated linkage connects the I support arms 38attached to the side members It].

A shaft. 39 is .rotatably mounted in the upstanding arms 3.8. The shaft39 carries and is keyed to the hub of a pan arresting element M .(Fig.2). The element 41 :carries .a plurality of radially directed stop arms.42 (Figs. .1 and 2.) which are equally spaced about the hub. Rollers 43are rotatably mounted at theends of the stop arms.

.A star wheel 44 is also keyed to the shaft .35

.at oneend thereoiand a pawl 46 :attachedto the pawl carrying rod 34 isadapted to en age teeth 41 of thestar wheel to hold theshatt 39 and stoparms 42 stationary. As shown in the drawings, each of the stop arms -42is adapted to extend as distance into a bakingpan .at thepan holdingstation 16?). However, the arms donot extend .to the bottoms of the pansso that loaded panscan pass under .the .stop member 4| and be .varrestedthereby without the stop arms substantially displacing dough loaves .inthe pans. ,As shown in Fig. 1, thespacing between stop arms 42'issuiiicient so that, when the pawlis released to permit the star wheelto advance one tooth, the stop arms release the pan at the pan holdingstation but catch and arrestthe next succeeding pan as the pansarepushed jbeneath the pan .arresting member.

Pans maybe placed on'the'belt 14 ahead ofithe loading stations and, asindicated at 48,301.18 dough conveyor support framework is cut away to@110- 4 advanced by the belt l4. The belt l4 may be made of materialwhich can slide beneath the pans when a pan is held by the stop member.The belts l4 and 24 may be continuously driven by driving rolls, notshown and, each time a dough loaf advances along the belt 24 to pass therelease flap 3| a pan held by the pan holding 1menrber released to ipassonto the roller con- :veyorJ-Zl and the next succeeding pan is arrestedby the pan holding member so that the pan at the loading station whenthe release flap is raised can advance toward the pan holding station16b,

and a new and empty baking pan can advance to then advances the pansonto the roller discharge .bonveyor 2 l.

The dough loaves may be formed in any appropriate machine and depositedon the dough c nveyor to advance al nsthe dough conveyor one at a time.The baking pans advance intermittently along the belt in and :across thetable .ll one after another, and a pan is :ad- .vanced to theloading-station only when a dough loaf raises the releasefiapsl. The panconveyor I belt advance s contir1uously, ,and when the pans are heldbythe .pan stop member-l9, the belt l4 slipsbeneath the ans The machineillustrated in the drawings and described above ,is subject tostructural ,modification without departing from .the spirit and scope ofthe appended claims.
